What to do if all lights are off except the 'Connected' light on Schumacher Battery Charger?

This happens if the battery didn't fully charge within 24 hours, possibly due to a very large battery or battery bank needing more power than the charger could provide in that time. The charger enters abort mode, or the battery may be faulty. To resolve this, reset the Schumacher Battery Charger by unplugging it. Then, select the desired charge rate and battery type again, if necessary.
